Which consequence occurs to photon behavior near a black hole's event horizon?

💡 Explanation

Gravitational lensing occurs because spacetime curvature increases near a black hole due to mass-energy equivalence, dramatically altering photon paths. Therefore, photons bend significantly, rather than exhibiting increased redshift or spontaneous emission, because these typically require external inputs rather than gravity alone.
